Re: FW: Parallel Server --> RAC

Here's the official line from Oracle:

In building RAC, Oracle discarded the old OPS technology. OPS customers may, of course, continue to run Oracle 8i as their database program if they prefer to continue to employ OPS. However, current OPS customers who wish to run Oracle 9i databases on clusters will need to migrate to RAC. To protect customer investments in OPS and to encourage customers to utilize the advantages of the new RAC technology, Oracle offers a net-to-net migration path. Supported OPS customers who choose to migrate their existing OPS licenses to new RAC licenses will receive a credit for the net license fees paid for the migrated licenses. This credit may be applied toward the purchase price of the new RAC licenses.

Isn't that a beauty? I never imagined this. We should all be grateful that Oracle has chosen to build on proven, tested technology instead of doing it all from scratch. GES and GCS hare pretty much the same since version 5. The new stuff added have various issues, by the way, as all new software has.

The reason RAC runs so relatively easy and stable is that it's a lot of stable, old, tested stuff with some new stuff added.

I love it.
